About Those Yellow Underarm Stains on Your Shirt

How many of your favorite shirts have you lost to a crusty, yellow stain that has mysteriously formed on its underarm? Worse—how many times have you seriously debated with yourself the point at which said stain would render your polo, tee-shirt or oxford too unsightly to wear? The crusty, yellow rash of shirt death is a real problem but there are ways for you to avoid or stave off this problem.

The culprit, it turns out, is your antiperspirant. More specifically, its active ingredient—aluminum. That’s pretty much a bum situation for the product since aluminum’s removal would transmogrify the antiperspirant into its less brawny cousin, deodorant.

Before the nitty gritty, a little refresher—antiperspirants work by plugging the sweat ducts and minimize sweat so odor causing bacteria can’t set up shop. Deodorants use ingredients that destroy the bacteria once they’ve signed the lease.

The safest, but probably most outlandish, is to just have your underarm sweat glands removed. Yes, that’s a thing (that also permanently removes your underarm hair so….) More realistically, you should just get a little better at reading the ingredient list. Of all the forms of aluminum, aluminum chlorohydrate is considered the least harmful to your shirt.

Use sparingly and let it dry fully before getting dressed—one light all encompassing swipe will keep you dry and expose less of the harmful ingredient to your shirt. This is also a smart idea if you’re one of those guys who get skin irritations from antiperspirant. Another way to help mitigate the problem is to wash with an antibacterial soap. This will help keep odor causing bacteria at bay and make it a lot easier for you to apply antiperspirant sparingly.

If you start to notice the onset of the killer canary color there are a few tricks that might work. Namely a mix of baking soda, hydrogen peroxide a dash of dish soap, which when scrubbed onto the spot with an sponge or brush has worked for me to temper the yellow color (but only at the onset). Hot and warm water will help set the stain so stick with cold water. Another option is to soak the spot in white vinegar, though that smells like, well, vinegar.

We’ve also got to mention, since being put to use in antiperspirant back in the 1940s, Aluminum has also garnered a bad reputation for having been linked to things like cancer, kidney disease, Alzheimer’s and the formation of breasts in men. It is, after all, an estrogenic.

Doctors are still squabbling about the definitive correlation between aluminum and certain death (and breasts), but we do know for sure, that it is the number one cause of nasty underarm stains. So maybe don’t even use it at all? That’s totally up to you, deodorant will keep you smelling fresh, but if you turn into a human sprinkler system come summer, the regiments described here will come in handy.

Dean Bell hits the road and talks men’s grooming
Adult, Male, Man

Dean Bell is a guy many people know from The Bachelor and The Bachelor in Paradise. He has since updated his image as an influencer searching for adventure. That search has led him to partner with Chevron this summer in celebration of the country’s 250th birthday. In addition to helping many drivers keep their engines in top shape this summer with his support of the gas, he is teaching us something he is adopting this season: Men’s grooming and skincare. As he gets a little older, he is figuring out, with the help of his wife (like most of us), the importance of taking care of his skin. But how is he doing that on the road this year? And how can we learn from his experience?

That’s what grooming is at the end of the day when it comes to skincare. You are basically keeping to your skin as youthful as you possibly can. – Dean Bell

Grooming is on its biggest stage with World Cup 2026
Ball, Football, Soccer

We don’t talk enough about men’s grooming. Skincare, haircare, nails, and teeth are all important for your personal appearance and overall health. Typically, we tend to put it on the back burner while we focus our time on things with a more measurable return on time investment. Sure, we used to get away with this because guys like John Wayne, Clint Eastwood, and Paul Newman were regarded as examples of the rugged male aesthetic that didn’t need the attention to moisturizing and conditioning. Nowadays, though, men like George Clooney and Brad Pitt are seen as sex symbols deep into their sixties, and it is largely thanks to skincare. Recently, if you have been watching the World Cup, you may have noticed a focus on the grooming marketing. That is because Unilever has launched its largest activation ever with a sponsorship of the FIFA World Cup 2026.

The FIFA World Cup 2026™ will be the most socially connected and inclusive tournament in our history. Football today lives in real time, in culture and on social platforms – and this tournament is designed to be experienced, shaped and shared by fans wherever they are. – Romy Gai, Chief Business Officer, FIFA

Your dad’s favorite gift may be smelling good
Bottle, Cosmetics, Perfume

As Father’s Day sneaks up on you (hopefully it isn’t sneaking up on you since we have been putting Father’s Day gift guides and articles with ideas for a few weeks here), there is a tendency to go for the old faithfuls dads seem to have always gotten. Ties. Mugs. Tools. And, of course, the always classic Old Spice cologne. The same cologne his dad got. The same cologne his grandfather got when your dad couldn’t figure out what to get him. It is time to do something different. Sure, a man wants to smell good, and buying him a cologne is a great gift. But you can do it the regular way, or you can go above and beyond by letting him make his own choices (I’m not talking about a gift card). Olfactory NYC is the kind of gift your dad is looking for this year.

A deeply personal experience
